Looking at selling a new SprintBooster for the E82/E90 (Automatic Transmission). This version has the removeable switch and allows 2-3 adjustable settings. I loved this thing. Makes the car more energetic. D now feels like DS. Need the money for bills!

Looking at getting $200 shipped in US. Includes original sticker/manual/etc.

How often do you feel that your car does not respond to your command ?''
''How often do you have to turn off the A/C in order to cross quickly a road with traffic?''
''How often do you feel that your car doesnot respond when going uphill?''

Vehicles in the 21st century have replaced the more conventional throttle cable technology for an ECM(Electronic Control Module) that translates pedal travel into electronic signals in order to provide power to the wheels.

The ETC system (Electronic Throttle Control) – also known as drive-by-wire –has the unfortunate downside of delayed throttle response and subdued acceleration, creating problems in certain circumstances such as up-hill starts, quick gear changes, overtaking, etc. The Sprint Booster aims to over come this throttle response delay for ETC-equipped vehicles, providing crisp on-tap acceleration at the driver’s disposal.

Sprint Booster might very well be the “smartest” gadget on your car.
It is a device that improves acceleration by continuously measuring and converting the digital signal provided by the ETC’s potentiometer, and providing the ECM with a new and altered signal.
The design of the SprintBooster allows for its easy installation in all models, without the need to cut any wires (plug n’ play) or intervene in the automobile’s electronics (it does not affect other systems such as electronic injection, ABS, etc.).
Sprint Booster connects on the accelerator pedal connector. All you need to do is disconnect the OEM connector from the accelerator pedal and connect Sprint Booster in between (one side connects to the pedal and one side on the OEM connector).

Results
Sprint Booster is aimed at all drivers with ECT-equipped cars, who are after a safer and more exciting automotive experience.

• At low revs, the engine responds at approximately half the time in comparison to before.
• The delay time whilst accelerating in 3rd and 4th gear and the engine in the mid-range,is almost zero.
• Big differences in the higher rev range.
• Improved response for down shifts and safer overtaking.
• Overall safety and more fun on the road!
